How to distinguish the bearing of vibration motor?

Vibration motor because of its special structure principle, through destructive eccentric operation to produce vibration, the quality of bearing selection is directly related to the quality and service life of vibration motor, of course, the price of vibration motor with different quality is also different. So how to distinguish whether the bearing is good or bad?

1. Look at the appearance: the letters on the surface of the original bearing are carved or sprayed, and the font has special design, while the printing of counterfeit products is fuzzy.

2. Look at the material. Standard bearing steel is selected as the material of original bearing, and cheap, inferior and unqualified materials are used for counterfeit products to reduce manufacturing cost and light weight.

3. Look at the packaging. The packaging of regular original bearing is generally more standardized, including inner packaging and outer packaging. The standard is unified and standard, and the handwriting is clear, while the packaging of counterfeit products is generally poor in material and rough in printing.
